Mathematics
1 answer:
sveta [45]3 years ago
8 0

Answer:

Step-by-step explanation:

(7,105) , (4,60)

slope = (y2 - y1) / (x2 - x1)

slope = (60 - 105) / (4 - 7) = -45/-3 = 15

y = mx + b

slope(m) = 15

(4,60)...x = 4 and y = 60

now we sub and find b, the y int

60 = 15(4) + b

60 = 60 + b

60 - 60 = b

0 = b

so ur equation is : y = 15x <===

how many pies must be made to make 165... so we sub 165 in for y in the equation and solve for x, the number of pies needed

y = 15x

165 = 15x

165/15 = x

11 = x <=== she would have to sell 11 pies

Find the solution of the system of equations.
avanturin [10]

Answer:

3

Step-by-step explanation:

The number is 3.

Step-by-step explanation:

Finding the Number

To find the number, we have to translate the problem above to an algebraic equation. The algebraic equation refers to the statement of the equality of two algebraic expressions.

Equation:

Let "x" be the number.

4 is divided by a number - 4/x

3 divided by the number decreased by 2 - 3/x-2

"4 is divided by a number is equal to 3 divided by the number decreased by 2"

4/x = 3/x-2

Solution:

Cross multiply.

4/x = 3/x-2

x(3) = 4(x-2)

3x = 4x - 8

(Combine similar terms.)

3x - 4x = - 8

- x = - 8

- x/- 1 = - 8/- 1

x = 8

Final Answer:

8

Checking:

4/x = 3/x-2

4/8 = 3/8-2

1/2 = 3/6

1/2 = 1/2 ✔

Write in standard form an equation for the line with slope 1/3 through<br> the point (2,-2).
Alexxandr [17]

Answer:

x - 3y = 8.

Step-by-step explanation:

Use the point-slope form of the equation of a line:

y - y1 = m(x - x1)  where m = the slope and (x1, y1) is a point on the line.

So substituting the given values:

y - (-2) = 1/3(x - 2)

y + 2 = 1/3x - 2/3     Multiply through by 3:

3y + 6 = x - 2

x - 3y  =  6 + 2

x - 3y = 8  <---- Standard Form.

Help pleaseee Im trying to get an A in class
likoan [24]

Answer:

191

Step-by-step explanation:

Sorry it's sideways. I drew a box chart for this. First, fill in what you know: the number of white and black beads Ally has. Then, calculate how many black beads Betty has (Ally's number, 59, minus 35.) 59-35 = 24.

They tell you the total number of beads is 346. Add up Ally's total to get 131, then subtract that from 346. That's Betty's total beads, 215.

Last, subtract the 24 black beads Betty has from the 215 total to get 191.
